Synthesis of 3-alkenylamines, 4-alkenylamines and 3-allenylamines via a transamination procedure
摘要:
3-Alkenylamines, 4-alkenylamines and 3-allenylamines were synthesized conveniently by potassium t-butoxide induced transamination of alpha-vinylaldimines, alpha-allylaldimines or alpha-allenylaldimines followed by hydrolysis with aqueous oxalic acid. (C) 1997 Elsevier Science Ltd.

日期:——
N-(Benzylidene)- and N-(alkylidene)-homoallylamines are cyclised by electrophiles, e,g. bromine or phenylselenenyl bromide, and by subsequent reduction to the corresponding 3-functionalised pyrrolidines; the stereochemistry was investigated, and reductive removal of the 3(or 4)-bromo- and 3(or 4)-phenylseleno-substituents was accomplished.
